Abstract

A vehicle signal light assembly (170, 172) includes : at least one color mixing light source (V, W, X, Y, Z); a support element (180) configured to support the at least one color mixing light source (V, W, X, Y, Z) on a vehicle as a signal light (170, 172); and a controller (200) configured to selectively drive each color mixing light source (V, W, X, Y, Z) to generate light of a selected visually perceived color based on a received control signal (R,G,B). In some such embodiments, each color mixing light source (V, W, X, Y, Z) of the vehicle signal light assembly (170, 172) comprises a plurality of light emitting diodes (LEDs) of at least two constituent colors. In some such embodiments, the controller (200) is configured to operate each color mixing light source (V, W, X, Y, Z)of the vehicle signal light assembly (170, 172) using time domain multiplexing (TDM) to generate the light of the selected visually perceived color. In some such embodiments, the vehicle signal light assembly (170, 172) comprises a taillight assembly. In some of the embodiments, the vehicle light assembly comprises an ambient or auxiliary lighting, or a dashboard lighting assembly.
